Snapshots timeouts
I am currently trying to create another hbase cluster by exporting snapshots
from our main storage.
While it worked well for the smaller tables, it failed on timeouts on larger
tables while trying to CREATE the snapshots.
I read a bit about it and found out that increasing
"hbase.snapshot.master.timeoutMillis" and "hbase.snapshot.region.timeout"
may help.
Where should I set those configurations?

Snapshots are a two-phase commit like operation, with the master
coordinating the region servers.
http://blog.cloudera.com/blog/2013/06/introduction-to-apache-hbase-snapshots-part-2-deeper-dive/
so, you have 2 timeout
- on master side you have to set "hbase.snapshot.master.timeoutMillis".
(The master is waiting response from every RS involved in the snapshot
operation)
- on region server side you have to set "hbase.snapshot.region.timeout".
(The region server is the one taking the snapshot of the regions that is
hosting)
the properties must be set in the hbase-site.xml of Master/RSs

HMaster hbase-site.xml!

There are actually three timeouts, and I only had success when increasing all
three. Adding the following to hbase-site.xml should do the trick.
<property>
<name>hbase.snapshot.master.timeoutMillis</name>
<value>1200000</value>
</property>
<property>
<name>hbase.snapshot.region.timeout</name>
<value>1200000</value>
</property>
<property>
<name>hbase.snapshot.master.timeout.millis</name>
<value>1200000</value>
</property>
